Abstract: A method for avoiding the spread of a thermal event in an enclosure containing several modules (1, 2, 3, 4) of electrochemical elements, said method comprising the following steps: —detecting one or more critical modules (1, 2, 3) situated in the enclosure, and affected by a thermal event (13), a module being critical when one or more parameters associated with the status of the module have reached or crossed a predetermined threshold, —spraying a coolant (12) onto, or into, the critical module or modules (1, 2, 3) for a determined duration and/or at a determined flow rate, one or more modules (4) not detected as being critical modules not receiving any coolant (12).
